--- Comment #4 from Michael Weiser <michael at weiser dot dinsnail.net> ---
Okay, I can see this is headed for a WONTFIX. Can you please answer my
questions before we chuck it?

1. How hard would it be or is there even some effort/patch to make gcc only
compile in support for a selected number of CPUs of a given target, indirectly
reducing size of insn-attrtab/insn-automata?

2. Incidentally: Is my patch likely to produce a seriously broken compiler?

Thanks!
